"Endless Forms Most Beautiful" is the eighth album by Finnish symphonic power metal band Nightwish. The album's themes primarily inspired by the work of naturalist Charles Darwin. This is the band's first featuring singer Floor Jansen and the first with Uilleann pipes player, Troy Donockley as a full-time member. It was also the first without drummer Jukka Nevalainen, who took a break from the band due to severe insomnia. Drumming was by Kai Hahto of Wintersun and Swallow the Sun. The album includes only five Nightwish members, despite its being their first album release as a sextet.

Nostalgia is a powerful tool. It’s been 16 years since the release of the album, but I easily remember what those days surrounding the release of the record were like. The excitement, the ambition, the comradeship, the triumphant tour to come, it was all there, about to carry the band to another level, musically and journey wise. “Once” instantly became Nightwish’s watershed album.
